Further, the input device 1 also includes a touch screen.
As shown in fig. 1 to 4, the number of the host computers in this embodiment is 4, taking the host computer as a server host computer as an example, the host computer 41, the host computer 42, the host computer 43, and the host computer 44 are connected to the display 100, and the host computer 41, the host computer 42, the host computer 43, and the host computer 44 simultaneously output image and sound data to the display 100. Specifically, as shown in fig. 2, after the display is turned on, the image signals of the host 41, the host 42, the host 43, and the host 44 are automatically detected, and if the host 41, the host 42, the host 43, and the host 44 all operate normally, the display 100 displays the image and the sound of the corresponding host on the display screen 8, and the screen is divided into 4 screen segments. There are 4 hosts, the display corresponds to at least 4 audio input interfaces, the audio input interfaces of the display 100 are all HDMI interfaces or all DP interfaces, or both HDMI interfaces and DP interfaces, and the audio and video signals of each interface can be displayed on the display separately. And 4 hosts are accessed into the display, the display screen simultaneously displays 4 pictures, if 2 displays are accessed, the screen is divided into two screens, and if 3 displays are accessed, the screen is divided into three screens.
As shown in FIG. 2, 4 hosts normally access the display, images of 4 hosts are all displayed simultaneously, and the control of the USB keyboard 12 and the USB mouse 11 controls the host 41 by default. Each host is connected to the USB switching module through a USB cable, and if it is desired to switch the control of the host 41 to the control of the host 42, as shown in fig. 3, the principle is: the host 41, the host 42, the host 43 and the host 44 are all provided with monitoring software, the monitoring software monitors input data of the input device in real time, after the host 41 enters an operating system, the monitoring software of the host 41 is started, the monitoring software can monitor coordinate values of the USB mouse of each host on a screen in real time, and when the coordinate values of the USB mouse stay in an area needing to be switched for a certain time, the switching action is triggered. The monitoring software of the host 41 detects the mouse coordinate of the host 41 in real time, and triggers the switching operation of the host 41 to switch the host 42 when the mouse pointer of the host 41 stays at the maximum value of the horizontal coordinate for a certain time. When the host 41 detects that a trigger occurs, the command sent by the host 41 sequentially passes through the USB switching module 3, the USB hub 2, the USB to I2C communication module 5, the I2C communication module 51, the main control MCU and the video processing module 6, as shown in fig. 1 and 4, the high and low potentials of the GPIO1 port and the GPIO2 port of the main control MCU and the video processing module 6 change, the GPIO1 outputs a high potential, the GPIO2 also outputs a high potential, the high potentials of the GPIO1 and the GPIO2 control the pins of the S0 and S1 of the USB switching module to input a high potential, the command is switched to the host 42 through the USB interface of the input device connected to the USB hub 2, and the USB hub module 3 is connected to the USB cable of the host 42, that is, the USB interface of the input device such as a mouse and a keyboard is connected to the. Similarly, the control of the host 2 is switched to the control of the host 3 or the host 4, so that the control of the hosts can be automatically switched, and a plurality of hosts can be automatically and freely controlled.
The 4 hosts are connected with the display, the screen is divided into 4 screens, the display areas of the 4 hosts on the screen are fixed, if a host in the 4 hosts fails, for example, no signal output occurs in the host of the host 44, the host is abnormally accessed into the display, the image area of the host 44 corresponding to the 4 divided screens of the display screen is also a black screen, the normally accessed display images of other hosts are not influenced, for example, the host 44 is subjected to black screen, the USB mouse cannot drag the screen image corresponding to the host 44, the mouse and the keyboard cannot be switched to the host 44, and the normally accessed display images of other hosts are not influenced.
The above is to trigger the switching of the USB interface connection of the input device by the coordinate value of the USB mouse, and the other switching method is to switch the input device by the USB keyboard. The host is normally connected to the display, the images of 4 hosts are displayed simultaneously, and the control of the USB keyboard and the USB mouse controls the host 41 by default. If it is desired to switch control of the host 41 to control of the host 42, as shown in fig. 3, the principle is: the host 41, the host 42, the host 43 and the host 44 are all provided with monitoring software, the monitoring software can monitor numerical values input by the USB keyboard of the respective host in real time, when the coordinate values of the USB mouse stay for a certain time in respective areas needing to be switched, the keyboard inputs a number of 2, the host 41 can monitor that, as the principle flow of the switching of the USB mouse is the same, the command sent by the host 41 reaches the main control MCU and the video processing module, the GPIO1 ports and the GPIO2 ports of the main control MCU and the video processing module all send high potential, and the command is switched to the host 42 through an input device connected with the USB hub. The input device further comprises a touch screen, the touch screen is connected with the USB concentrator, the touch screen is a display screen, the touch screen slides in a touch mode, and the USB connection switching mode is the same as the mouse switching principle, and the description is omitted here.
Each host can access the same network, and at the moment, one person can simultaneously operate a plurality of hosts, and because of the access to the same network, files of each host can be exchanged and transmitted, sometimes large files of two hosts need to be mutually transmitted, and a mobile hard disk or a U disk with enough size is not available. At this time, the host can access the same internal network to share resources, and the file of the host 41 is transmitted to the host 42, so that a plurality of hosts can be efficiently controlled, and the labor cost is reduced. When the hosts are accessed to different networks, the accessed networks are different, and the network sharing folder cannot be accessed to the same network due to the access authority, the firewall, the IP protocol and the like, the hosts are accessed to different networks to ensure the data security of the hosts, the hosts are isolated from each other, and the files of the host 41 cannot be transmitted to the host 42 on the same display screen, for example, a doctor needs to write a report while performing video communication with a remote doctor and shooting the report while watching a patient. Because the host computer all is the different networks of access, for example remote host computer need access to the internet, see the intranet that will insert the hospital of piece, if someone invades remote host computer, can not invade the host computer that can see the piece, the security is high. The host can be a smart phone host, taking the host as the smart phone host as an example, the smart phone outputs audio and video data to a display screen of a display through a wireless screen projection module, and is connected with a USB switching module through a USB cable or WiFi or other wireless connection modes to be communicated with a main control MCU and a video processing module of the display. The invention can improve the efficiency of workers, can efficiently control a plurality of computers, reduces the labor cost, can automatically switch the control of the host, realizes automatic and free control of a plurality of hosts, and solves the problem of low working efficiency caused by that the workers operate the hosts to switch input equipment back and forth.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings and the working principle of the present invention is explained, but the present invention is not limited thereto, and various changes made within the knowledge of those skilled in the art without departing from the gist of the present invention are within the scope of the present invention.
